1. Masturbating with tranquillity until you finish, then you feel immediate shame for jerking off/ jerking in (if female)
2. Jerking off the something that gives you shame (Hentai, loli porn, BDSM)
Man 1: Hey dude, I think I had a Shame Jerk yesterday. Everything was going good until I finished and then I realized jerking off to loli porn is not ok!
Man 2: same thing happens to me when I bust, except I always feel shame for doing such a disgraceful act while looking at a picture of my sister
When a guy masturbates without any tissues for cleanup, so he has to sadly wipe the resultant semen on the side of the bed closest to the wall after he’s done with his stroke session.
I forgot that I didn’t bring any toilet paper into my bedroom last night, I was forced to do the wipe of shame.
